Abstract (en)
[origin: WO2015044303A2] The invention relates to an eyeglass lens for a display device (1), which display device can be placed on the head of a user and generates an image, said eyeglass lens comprising an eyeglass lens body (7), which has a front side (8) and a back side (9), wherein the front side (8) and/or the back side (9) is curved and the eyeglass lens body (7) has at least one first and one second partial body (35, 36), the boundary surfaces (38, 39) of which facing each other are in direct contact, and comprising, as viewed in a top view of the eyeglass lens (3, 4), a coupling-in section (17) in an edge region (12) of the eyeglass lens (3, 4) and a coupling-out section (16) in a center region (13) of the eyeglass lens (3, 4), wherein the eyeglass lens (3, 4) is suitable for conducting light bundles (24) of pixels of the generated image, which light bundles are coupled into the eyeglass lens (3, 4) via the coupling-in section of the eyeglass lens, in the eyeglass lens (3, 4) to the coupling-out section (16) and for coupling said light bundles out of the eyeglass lens (3, 4) via the coupling-out section (16), wherein a flat first reflection surface (18, 31) and a flat second reflection surface (19, 32) spaced apart from the first reflection surface (18, 31) are provided in the eyeglass lens body (7), which reflection surfaces each extend in a direction from the coupling-in section (17) to the coupling-out section (16) and are each spaced apart from the front side (8) and the back side (9) of the eyeglass lens body (7), wherein the light bundles (24) are guided in the direction from the coupling-in section (17) to the coupling-out section (16) by means of reflections on the two reflection surfaces (18, 31; 19, 32), and wherein at least one of the first and second reflection surfaces (18, 31; 19, 32) is provided in the first or second partial body (35, 36) and is offset from the boundary surface (38, 39) of the corresponding partial body (35, 36) in the direction from the first to the second partial body (35, 36).
